FIELD OF INVENTION

This invention relates to jewelry items and jewelry sets which include improved interchangeable decorative elements as well as methods of manufacture and use of same.

BACKGROUND OF THE INVENTION

Prior art attempts to design interchangeable jewelry systems have typically focused on relatively expensive fine jewelry market segment, rather than more affordable costume jewelry market. One example of such prior art systems is disclosed in U.S. Pat. No. 2,752,764 which shows an earring body having a flat magnet permanently attached to it, surrounded by a collar, the collar having an opening on its periphery. The removable button, or other ornamentation fits into the cap created by collar, and has, on its inside a flat armature which rests on the flat magnet mounted on the body of the earring when the unit is assembled, as shown in FIG. 3 of the '764 patent. The flat armature of the earring body is also made of a magnetizable material so that the earring design includes two magnets of opposite polarity. The ornamentation is disclosed as being a semi-precious or precious stone as is appropriate for a fine jewelry piece. The ornamental portion is held so tightly by the opposite polarity magnets and collar that an aperture is provided through the collar for the purposes of allowing entry of a prying element to permit separation of the ornamentation portion from the body of the body of the earring. The applicant believes that the relatively complex design of the heavy weight clip-on style interchangeable jewelry systems of the '764 patent is too costly to be competitive in the more cost conscious costume jewelry market to which the present invention is primarily directed.

Another prior art approach to interchangeable jewelry is disclosed in U.S. Pat. No. 6,594,871, which shows jewelry pieces with replaceable ornamental elements having a decorative exterior surface and a frame. The '871 patent further discloses that the replaceable ornamental element are readily removable yet securely fixed when engaged to allow the ready substitution of another element having an exterior surface of different decorative character. The '871 patent asserts that the ornamental elements can be incorporated into “a cuff link, an earring, a stud for a tuxedo shirt, a ring or a pendant to the wearer's apparel and/or accessories.” The '871 patent further discloses the use of a first magnet fixed to the bottom of said decorative element and least one other magnet being fixed to and arranged within the recessed portion of the frame for securing said decorative element therewithin. The connection between the two portions is so secure that magnetically attached portions of the designs include an aperture extending through the bottom of the recessed portion of the frame for providing access for a stylus for selectively dislodging the decorative element from the frame. In the applicant's view, the jewelry designs of the '871 patent are also too complex and costly for use in the mass market costume jewelry field.

OBJECTS OF THE INVENTION

Accordingly, an object of the invention is to provide an interchangeable jewelry system and jewelry pieces having cost efficient designs that can be manufactured for sale as mass market costume jewelry.

Another object of the invention is to provide a simple and inexpensive interchangeable decorative jewelry elements that can be utilized across different jewelry pieces of a line to provide the opportunity for the jewelry wearer to color coordinate, complement or contrast with clothing, the wearer's physical attributes such as eye color, or other fashion accessories in a cost effective manner.

Another object of the invention is to provide an inexpensive interchangeable jewelry line having decorative elements designed to be mass producible at sufficiently low cost that they are virtually disposable in order to satisfy the youth costume jewelry market.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A first embodiment of the invention is shown in FIGS. 1-9, which depict an interchangeable post-style earring 20 of the invention. This style earring includes a base 40 including a post portion 21, backing 22, planar surface 23, and magnetic portion 24. The base portion 40 is releasably coupled to decorative cap 25. The post 21 is for placement through a pierced ear with backing 22 designed to engage the back surface of the earlobe and planar surface 23 contacting the front surface of the earlobe. A magnetic portion 24 is permanently joined to the planar surface 23 in the embodiment shown in FIGS. 1-5, but the base portion and magnetic portion could be integrally formed in one piece. The magnetic portion 24 has a peripheral edge 29 which is dimensioned for receipt within an outer rim 30 formed at the periphery of the back surface 31 of the decorative cap portion 25. The back surface 31 of the decorative cap 25 is held against the front surface 32 of the magnetic portion 24 by the force of magnetic attraction since the receiver portion 26 of the decorative cap 25 is formed from a magnetizable material. When outer rim 30 engages peripheral edge 29, it helps to seat the decorative cap portion on the magnetic portion 24. Preferably, the inner diameter of the outer rim 30 is slightly larger than the outer diameter of the magnetic portion 24 so that a small gap is formed between the peripheral edge 29 of the magnetic portion 24 and the outer rim 30 of the decorative cap 25. The presence of this gap facilitates purposeful decoupling of the decorative cap 25 from the base 40 of the earring 20. The preferred gap is about 1 mm with gaps of about 0.5 mm to 1.5 mm being acceptable. Magnet 24 preferably has an external diameter of 10 mm, with external diameters between about 9 mm and 11 mm being acceptable. Cap 25 preferably has an internal diameter of about 11 mm with between about 10.5 mm and 12 mm being acceptable, and cap 25 further has a preferred external diameter of about 12 mm with 11.5 to 13 mm being acceptable.

The receiver portion 26 of the cap portion (best seen in FIG. 3) can be formed from a variety of magnetizable metal materials including alloys of iron, nickel, cobalt and/or manganese. The receiver portion may be molded from liquefied metal by a forging process or molded from a flowable metallic powder by metal injection molding. Alternately, the receiver 26 can be formed stamped from metal disk blanks of magnetizable metallic material. Preferably, the receivers of the invention can be manufactured with different surface finishes and colors. For this purpose, coloring agents may be added to the liquefied or flowable magnetizable material prior to molding. Alternately, the receivers of the invention may also be brushed or dipped in a surface finish agent after molding to provide an antique finish or a brushed metal look.

As can be best seen in FIGS. 2-5, the decorative cap 25 includes a thin layer of decorative material 27 that is permanently affixed or adhered to the front surface 33 of the cap. The decorative material 27 may be any thin layer of material that is inherently decorative (such as a thin sliced layer of a semi-precious gemstone) or may be any material that can receive a decorative pattern thereon. In order to minimize the cost of production for the mass market or youth market, the preferred decorative material 27 is a paper piece upon which an attractive decorative pattern has been printed. If the decorative material 27 is paper, it is preferably enclosed by cover 28, which is either transparent or translucent. The cover 28 may be made from a material that imparts a gloss, sheen, brushed metallic look or other desirable surface finish to the decorative material 27. The cover 28 can be omitted if the decorative material is sufficiently durable to be exposed directly to the environment and if its surface finish is sufficiently aesthetically appealing. Referring now to FIG. 3, the receiver portion 33 of the decorative cap 25 is slightly recessed from raised edge 37 and joined to the receiver portion 33 by transition portion 35. The inner-diameter of receiver portion 33 is slightly larger than the outer diameter of decorative element 27. The dimensions and arrangement of the inwardly angled transition portion 35 help to center and seat the decorative element 27 in the receiver portion 33. The outer diameter of cover 28 is slightly smaller than the inner dimension of the raised edge 37. The cover portion 28 may be deposited as a flowable liquid resin that cover the entire decorative element 27 and at least a portion of the transition portion 35, but is deposited in a small enough quantity that it does not cover the raised edge 37. The flowable liquid resin would then be cured to harden it and assist in bonding it to the decorative element 27 and transition portion 35. Alternately, the cover 28 can be a thin translucent or transparent plastic disk that is adhesively affixed to decorative element 27 and/or transition portion 35.

The decorative cap 25 of the stud earring 20 is dimensioned to be interchangeable with the other interchangeable jewelry bases in the jewelry pieces or matched sets of the invention, for example, the dangling earring base 140 of FIG. 11 or the pendant jewelry base 240 of FIG. 12. To accomplish the interchangeable nature of these jewelry pieces, the peripheral edges 129 and 229 of the magnet 124 of dangling earring 120 (FIG. 11) and magnet 224 of pendant 220 (FIG. 12) are dimensioned to be slightly smaller than the outer peripheral dimension of outer rim 30 of decorative cap portion 25. In this way, the same decorative cap 25 can be used interchangeably with each of these three different jewelry bases 40, 140, and 240 to form three different jewelry pieces 20, 120, and 220.

Furthermore, the interchangeability feature allows for the matching of multiple interchangeable base jewelry pieces with sets of caps bearing the same design. Thus, a customer who has purchased multiple interchangeable bases of the invention could also purchase a set of four identical caps and have matching earring (either with the dangling or post type earring) and a pendant to wear as a matched set. The purchase and use of multiple sets of matched decorative caps each having the same decorative elements within a set, but different decorative elements between different matched sets, allows the purchaser to inexpensively match, contrast and/or complement a garment, physical attribute of the wearer or fashion accessory. The decorative cap in a matched set can be worn with any of the different interchangeable jewelry bases of the invention whether post-style earrings, dangling earrings, pendants, rings (not shown), or necklaces (not shown). Thus the wearer can choose a matched set of decorative caps that best matches, contrasts with or complements a given garment, wearer's physical characteristic, or accessory from among the plurality of matched sets of decorative caps. Then, the wearer can create the matched set of jewelry items by choosing a plurality of interchangeable jewelry bases for receipt of one of the matched set of decorative caps. Next, the selected set of decorative caps is detachably coupled to the selected set of interchangeable jewelry bases to form a matched set of jewelry pieces. Furthermore, the matched sets of decorative caps can be organized and held for easy storage and visualization on a magnetic board 60 illustrated in FIG. 13. This allows the owner of the decorative jewelry pieces to easily visualize the possible matches and/or combination of mismatched cap sets that the owner may utilize. For example, the owner may decide to use mismatched decorative cap sets that share a common design theme, color or pattern. Moreover, the magnetic board 60 is sufficiently portable that the entire unit with all the decorative cap sets can be packed in a suitcase so that the owner has the full range of choices of decorative caps when traveling. This can facilitate the process of packing for a trip by allowing the owner to bring a full range of matched decorative cap sets. In this way, the owner can avoid the laborious task of selecting complementary or matching jewelry for each outfit packed for a trip.

Permanent Magnet 24 is affixed to planar surface 23 via a suitable industrial adhesive. Base portion 40 is preferably formed of a material matched in color and surface treatment with cap 25. Typically, both the receiver portion 26 of decorative cap 25 and the base 23 are formed from a nickel alloy to provide a shiny surface finish and provide corrosion resistance to the jewelry.

The backing portion 22 (best seen in FIGS. 9-10) is formed from a thin, resilient metallic blank which retains a spring like memory when arms 22 a are curled inwardly to form a narrow gap therebetween for receipt of post 21 of base 23. Post 21 has a slightly larger external diameter than the narrow gap so that arms 22 a grasp post 21 when it is inserted through aperture 22 c. Further, arms 22 a each have a central groove 22 d that helps to center and align 21 when it is passing between spring arms 21 a. Backing portion 22 also preferably includes a pair of small peripheral apertures (not shown) which are designed to be received by a pair of retainers to facilitate bending of the arms 22 a during manufacture of same. The earring backing may be formed from thin metallic blanks that are bent into the curled arm position by inserting the blank into posts and then bending them over a pair of rod structures to form spring arms 21 a.
